Hi there, just wanted to share with you my little build.
Startet out with reading page up and page down on this forum and asking a lot of noob questions :p
Bought ~10 pcs 10W led of ebay, some 120mm fans and got some heat sinks locally to start a first prototype:
Don't have a lot of pics in this early stage, but i pre drilled some holes and mounted the leds on this heat sink and installed the 120mm (19db, can't hear it) on the back side:
This will then put out about 80 watt of LED light in a 200L tank.
And in a -totally- dark room they performed like this:
About 2-2,5 meters to the wall there.
After running the lights a couple of hours i measured the temp to ~23 degrees C, witch where about 4-5 degrees over the room temp, not bad at all.
Have been running this prototype setup for 1-2 months now, can't complain at all, very bright!
The tank on the top to the left.
All the other is 2 x 30W T8 (no reflector's).
So i started to make a more final design, one that is a little more safe and have a higher WAF :p
Ripped out the internal stuff and started measuring
Drilled holes and started to figure out on how to fasten things
(the one in the middle is just to illustrate)
Now we're just waiting for the some more LED's to arrive
Then I'll wire and solider things up.
If this works out, i'll make 4-5 more of these, but the number of bolts used here is totaly overkill, just like the amount of light.. as we like it
The original reason why I started reading up on LED's was to lower my power bill.. now I have gone from 2*30W to ~80W .. o'well.
Feedback, both positive and negative, are appreciated!
